add favicon to next js static site

1. Create a public directory in the root of your Next.js project if it doesn't already exist.

2. Inside the public directory, add your favicon.ico file. You can use an online tool to generate a favicon.ico file from an image.

3. Open your next.config.js file in the root of your project (create one if it doesn't exist).

4. If you don't have a module.exports block in your next.config.js file, add one.

module.exports = {
  // Your other configuration options go here
};

1. Inside the module.exports block, add the following code to configure Next.js to use the favicon:

module.exports = {
  // Your other configuration options go here

  // Configure the Next.js app to use a custom favicon
  async headers() {
    return [
      {
        source: '/favicon.ico',
        headers: [
          {
            key: 'Content-Type',
            value: 'image/x-icon',
          },
        ],
      },
    ];
  },
};

1. Save your changes to the next.config.js file.

2. Start or restart your Next.js development server:

npm run dev

Your favicon should now be visible when you access your Next.js static site.
